From a physiological standpoint, PRP works by initiating a cascade of cellular processes that contribute to hair follicle rejuvenation. Platelets release growth factors, which promote the formation of new blood vessels and stimulate the proliferation of dermal papilla cells. This, in turn, enhances the survival and function of hair follicles, leading to thicker, healthier hair growth.
For men experiencing male pattern baldness (androgenetic alopecia), PRP therapy can help slow down hair loss and promote the growth of new hair in areas of thinning. In women, PRP is effective for various types of hair loss, including female pattern hair loss, postpartum hair shedding, and alopecia areata.
PRP treatments are typically administered as a series of sessions spaced several weeks apart. During each session, a small amount of blood is drawn from the patient and processed to isolate the platelet-rich plasma. The PRP is then injected into the scalp using fine needles or applied topically following microneedling to enhance absorption.
Patients undergoing PRP therapy for hair restoration often experience gradual improvements in hair thickness, density, and overall scalp health over the course of several months. While individual results may vary, many patients report satisfaction with the outcomes of PRP treatments, particularly when combined with other hair restoration modalities such as minoxidil or micro-needling.
It’s important to note that PRP therapy is not a one-size-fits-all solution, and its efficacy can depend on various factors, including the underlying cause of hair loss, the extent of hair thinning, and individual patient characteristics. As with any medical procedure, thorough consultation is recommended to determine whether PRP therapy is a suitable option.
